Network Topology Visualization Overview
Topology visualization enables network administrators to view the complete network topology and its components. By monitoring the network topology, network administrators can monitor network health and plan changes to the topology to keep it functioning optimally.
The topology map in the Topology (Observability > Topology) page in Paragon Automation displays the network topology. The topology map is interactive, and you can customize the map to view the information that you choose. The network information table displayed at the bottom of the page enables you to view detailed information about links, devices, sites, and tunnels in your network and also customize your topology map view.
You can use the Topology page to perform the following tasks:
-
View network topology in the interactive topology map—The topology map displays the devices, the sites where the devices are located, and the links and tunnels between the devices in your network. The map is a representation of the network, and you can reload the map to refresh the network view. The devices on the map are identified by their hostnames. You can also change the labels to identify devices by their interfaces and IP addresses. You can view the real-time changes in your network if you enable the dynamic topology feature.
For more information, see Topology Map.
-
View live changes in your network—The topology map displays the live changes in your network. Paragon Automation establishes a BGP-LS peering session with the devices in your network, and enables you to view live changes in your network even if you do not adopt the devices in your network.
For more information, see Topology Menu Bar.
-
Manage the physical position of devices in the topology map for visual clarity—If there are many devices clustered together on the map, you can move the devices as per your personal preference or distribute them for easy viewing.
In Device View, the devices and links are displayed as per their coordinates saved in Paragon Automation. To manage the device positions and map layout, right-click a blank space in the map in Device view, click Layout, and select one of the available options. You can also import and export device location information in comma-separated values (CSV) format or GeoJSON format files.
For more information, see Topology Map.
In addition, you can switch between Device or Node View and Cluster View. In cases where devices and links are in proximity in the map, they might overlap with each other and clutter the map. In cluster view, you can collapse devices and links in the topology map into clusters and bundles to view them clearly. Clusters and bundles are aggregated forms of multiple devices and links and reduce the number of network elements visible on the map. Use the vertical topology menu bar on the right to switch between the default device view and cluster view.
For more information, see Topology Menu Bar.
-
View detailed information about the components in your topology in the network information table—The network information table at the bottom of the page displays detailed information about devices, links, and sites in your topology.
Click the Device tab in the network information table to view information about the devices in your topology. View information such as the site where the device is deployed, hostname, IP address, hardware, and severities of the alerts and alarms raised on the device. Alerts and alarms are collectively referred to as events in this topic.
For more information, see About the Device Tab.
Click the Link tab in the network information table to view information about the links between your devices. View information such as interface names and the IP addresses of the ingress and egress ports of interfaces connecting the devices. In addition, you can click a link to view information about interface statistics and status of the link.
For more information, see About the Link Tab.
Click the Site tab in the network information table to view information about the sites where the devices are located in your topology. View information such as site name, the number of devices in the site, and the severities of the events raised for all devices in the site. In addition, you can also configure new sites from this tab.
For more information, see About the Site Tab.
Click the Tunnels tab in the network information table to view information about all label-switched paths (LSPs), also known as tunnels, in your network.
For more information, see About the Tunnels Tab.
-
View severities of events—You can view severities of the events in the Device and Site tabs. The Device tab displays the total events raised on each individual device and the Site tab displays the total events generated for all devices in each site. To view more information about the events and to take action to fix the event condition, click the device name to navigate to the Observability > Troubleshoot Devices > Device-Name > Overview tab.
The Overview tab displays the different network component accordions along with their corresponding health status. If a device has an event, the severity of the event is displayed on the top right of the accordion. Expand the accordion with the event you want to view and perform the necessary action to fix the event condition.
